At old age, as people depend on superficial clues when they interpret the overall context of communication, their ability to understand connotative and figurative words and articles could deteriorate. In this study, 50 normal young(junior) people and normal old(senior) people were made to perform a task to understand similes, metaphors, idioms, and proverbs, the sub-areas of figurative language. For the task, participants were made to understand a paragraph consisting of several sentences and select a correct answer representing appropriate figurative language. As a result of the analysis, first, old people showed a lower level of performance than young people in all the sub-areas of figurative language. Second, in understanding idiomatic words and proverbs, old people showed a lower level of performance due to unfamiliarity. Third, for the types of wrong answers, old people mostly understood only the literal meanings in all the sub-areas of figurative language. Due to aging, old people come to have a lowered level of the pragmatic language ability, reasoning ability, and inhibiting ability to efficiently communicate with others considering certain situations and contexts. Thus, old people could have difficulties in understanding inner meanings from others in daily communication.

Currently, geographical information is interpreted and adopted in a wide range of context, and used for meeting diverse demands, such as, battlefield, traffic management, or public safety. With such an explosive increase of location-based applications, a considerable amount of research on the localization technique has been carried out. Among them, RSS (Received Signal Strength)-based approach is used especially for the indoor localization due to intrinsic limitations of the indoor environment. In this paper, we perform theoretical and empirical studies on enhancing the accuracy of the RSS-based localization on the IEEE 802.15.4 network. To this end, we set up an indoor testbed and implement a localization system on it. In addition to the theoretical analysis of the localization algorithm that we used, an empirical analysis on the effect of the factors which affect the accuracy of a localization system is carried out. Finally, we suggest some critical guidelines that should be considered for building a highly accurate localization system.

The purpose of this study is to understand the context of cosumers' lives in Korea with a narrative analysis method. The epistemological orientation of eh narrative analysis is Interpretivism, which blends the two polar philosophical perspectives, Empiricism and Rationalism, and includes Narrotology, Hermeneneutics, Semiotics, and Structural Criticism. Narrative analysis takes as its object of investigation the story itself. This study collects eleven narrative plots from four housewives, into which Labov's structural approach is applied. This study shows clearly that the socio-cultural environment in which consumers live has strong influence on their consumption behavior and also reveals that narrativization tells not only about past actions but how individuals understand those actions, that is, meaning.

Examining the experiences of different generations, this study assesses the subjective well-being(SWB) from eudaemonic perspective. Data was drawn from a survey of 1,214 adults in Korea. This research conducted descriptive statistics and multivariate regression analysis. Results show that even assessed from eudaemonic approach, material factors are still essential in explaining the variation of SWB. People in industrialization generation are less happy than other generations. Satisfaction with family and different types of social participation activities are related to SWB. This study suggests needs for focused attention on the factors affecting SWB in each generation.

The objective of the present study is to investigate the relationships among the perceptions of performance appraisal politics(POPAP)), employee's attitude to work, and team-based work system characteristics. Using survey data from various occupationally heterogeneous sample of white-collar employees(N=195) from various organizations, the results indicate that when employees perceive performance rating to be manipulated because of rater's personal bias and punishment motive, they reduce organizational commitment. Contrarily, the employees' POPAP with motivational motive increases organizational commitment. And task interdependency has positive effect on employees' POPAP.

This study focuses on the characteristics of information seeking behavior through the casual interactions which are regular contacts with others as information sources in the context of ELIS. Qualitative data were gathered using semi-structured one-to-one interviews with 9 wild-goose mothers in order to investigate the casual interactions. We identified information needs, patterns and characteristics of information seeking behavior through the casual interactions and the major interpretative repertoires.

In this study, pre-service science teachers' reflective thinking in their journal writing was investigated. To do this, the authors used pre-service science teachers' journal writing abilities, wherein they not only reported data and result formally, but also wrote their feelings and reflections about an inquiry-based physics experiment they performed. Pre-service science teachers' writings were decomposed into sentences and each sentence was analyzed into a framework with 4 dimensions: knowledge, procedure, orientation and attitude. Reflective thinking in knowledge dimension included reflection on what they know before the experiment, what they still do not know and what they learned from the experiment. Reflective thinking in procedure dimension included recalls of experiences about general experimental procedures and specific experimental skill. Reflective thinking in orientation dimension included their views about the nature of science and science teaching and learning, and reflective thinking in attitude dimension consisted of interests, motives and values about the experiment they performed. While there were some variations in frequency distribution of reflective thinking by the topic of experiments, pre-service science teachers' reflective thinking in journal writings revealed their metacognition on their knowledge and learning, epistemological belief about science and science learning, and affective domain related to experiment. This study can infer that such kind of writing with 'their own language' in an informal way followed by formal 'scientific' reports in a scientific experiment has a significance not only as a mediator representing reflective thinking but also as an instructional activity to facilitate reflective thinking in science learning and teaching.

다수의 태스크를 처리 가능하면서 일반화된 성능을 제공할 수 있는 모델을 구축하는 자연어 이해 분야의 연구에서는 멀티태스크 학습 기법에 대한 연구가 다양하게 시도되고 있다. 또한, 자연어 문장으로 작성된 문서들에는 대체적으로 시간에 관련된 정보가 포함되어 있을 뿐만 아니라, 문서의 전체 내용과 문맥을 이해하기 위해서 이러한 정보를 정확하게 인식하는 것이 중요하다. NLU 분야의 태스크를 더욱 정확하게 수행하려면 모델 내부적으로 시간정보를 반영할 필요가 있으며, 멀티태스크 학습 과정에서 추가적인 태스크로 시간적 관계정보를 추출하여 활용 가능하다. 본 논문에서는, 한국어 입력문장의 시간적 맥락정보를 활용할 수 있도록 NLU 태스크들의 학습 과정에서 시간관계 추출 태스크를 추가한 멀티태스크 학습 기법을 제안한다. 멀티태스크 학습의 특징을 활용하기 위해서 시간적 관계정보를 추출하는 태스크를 설계하고 기존의 NLU 태스크와 조합하여 학습하도록 모델을 구성한다. 실험에서는 학습 태스크들을 다양하게 조합하여 성능 차이를 분석하며, 기존의 NLU 태스크만 사용했을 경우에 비해 추가된 시간적 관계정보가 어떤 영향을 미치는지 확인한다. 실험결과를 통하여 전반적으로 멀티태스크 조합의 성능이 개별 태스크의 성능보다 높은 경향을 확인하며, 특히 개체명 인식에서 시간관계가 반영될 경우에 크게 성능이 향상되는 결과를 볼 수 있다.

Teachers play a key role in designing a students' learning experience. Teachers are asked to interpret the context in which they are located and to adjust their practice to fit circumstantial needs based on their teacher agency. In this study, we explore the emergence of teacher agency in distance learning caused by COVID-19 and we analyze factors shaping the teacher agency. For this purpose, we interviewed six secondary science teachers who practiced distance learning in 2020. Semi-constructed interviews and their artifacts were collected and analyzed. This study shows that teacher agency is captured when they respond to circumstantial change and modify their practice to achieve their professional purpose or adjust their practice in space for maneuvering or keep their practice consistent. This study also analyzes the factors that affect the emergence of teacher agency in two dimensions. One is individual and the other is contextual. In the individual dimension, educational values shaped by his/her experiences and short/long-term goals for the future support the emergence of teacher agency. In the contextual dimension, there are collaborative and flexible culture shared by the community, co-operation within the teacher community, and material support. On the other hand, in the individual dimension, the teachers' sense of their role, and no reflection for own practice constrain the emergence of teacher agency, and in the contextual dimension, performativity discourse and strong requirement without guidance constrain the emergence of teacher agency. We suggest an effective lens for establishing a strategy that support teachers' professional practice and the emergence of teacher agency.
